Title: Speed change gear
Inventor: KUWABARA MASAYUKI
IPC: F16H25/20
Filed: 1987-06-12
Abstract: PURPOSE:To set the speed change ratio arbitrarily by forming first and second threads whose lead angles are different to each other in unrotatable member capable of moving in the axial direction, and fitting a rotatable drive member incapable of moving in the axial direction to the first screw while a follower member capable of rotating only to the second screw. CONSTITUTION:A moving member 10 moves in the axial direction through a first screw 11 when a drive member 6 is rotated. A follower member 8 rotates through a thread 12, accompanied by the movement, and at that time the speed change ratio between the drive member 6 and the follower member 8 is determined by the lead angles of the first and second threads 11, 12. An arbitrary speed ratio is given by selecting the lead angles of the threads 11, 12 accordingly, and further a speed change device in high accuracy and strength is obtained cheaply by adopting high precision screws such as ball screws used in general purpose. It is possible to facilitate wiring and piping by forming a through-hole in the axial core direction on the moving member 10, and using this unrotatable through-hole in which the wiring and piping are arranged.
